Flashcards in 010514 vm Deck (17):
1

serous vs mucous acini-what are their differences

nuelci of mucous cells are flattened
those of serous cells are oval

2

serous demilune

arrangement in which mucous acini are covered by serous cells

3

gland composition in parotid, submandibular, and sublingual glands

parotid: serous
submandibular gland: mostly serous, some mucous (serous MORE)
sublingual gland: mostly mucous, some serous

4

circumvallate papillae

largest papillae on tongue and the least common
have deep cleft around

5

fungiform papillae vs filiform papillae

filiform papillae are short

6

skeletal muscle fibers are present in which part of esophagus

upper and middle third

7

epithelium changes how from esophagus to stomach?

stratified squamous to simple columnar

8

where are chief cells located? (as in portion of the stomach)

in fundic portion

9

large, round, eosinophilic cells with central nuclei in the gastric glands

parietal cells

10

histologic organization of 3 major salivary glands

secretory portion of parenchyma and stromal tissue
secretory portion has serous and/or mucous cells arranged in tubules or grape clusters called acini

duct system has hiearahcy or 3 types-intercalated, striated, and excretory

11

each salivary gland is divided how?

connective tissue capsule forms septae that penetrate the parenchyma of the gland to divide it iunto lobules

septae also carries vascular and neural components to the secretory cells and ducts

12

intercalated ducts

smallest ducts in salivary gland

13

striated ducts

several intercalated ducts merge to form striated ducts in salivary gland

14

excretory ducts

striated ducts join to form excretory ducts in connective tissue septa of salivary gland

15

intralobular ducts

intercalated ducts and striated ducts within the parenchyma are called intralobular ducts

16

what structure is at the jxn of stomach and duodenum?

pyloric sphincter--you will note pronounced muscularis externa

17

what structure is at the jxn of stomach and duodenum?

pyloric sphincter--you will note pronounced muscularis externa
